No changes. I can login as local administrator (administrator@vsphere6.lo<wbr />cal) but not as my domain username.

Yes, it is joined to the domain. Clocks are in sync. I was able to login earlier again and I logged out to test it again and started receiving the same error :(

I used to be able to access VSphere and all of a sudden we started receiving the error: &quot;Error Connecting. Cannot complete login due to &nbsp;an incorrect username or password.&quot; I already checked there is a PTR and DNS record. I already rebooted the PSC vm. &nbsp;I can login to PSC with admin credentials. I also confirmed the domain is added under Identity Sources. &nbsp;Is there anything else I can try?

The Domain Name System (DNS) is a hierarchical, globally distributed system responsible for associating the name of a computer, service or other resource into an IP address for connecting to the Internet or a private network. Most prominently, it translates domain names to the numerical IP addresses needed for the purpose of computer services and devices worldwide.

VMware, a software company founded in 1998,  was one of the first commercially successful companies to offer x86 virtualization. The storage company EMC purchased VMware in 1994. Dell Technologies acquired EMC in 2016. VMware’s parent company is now Dell Technologies.

VMware has many software products that run on desktops, Microsoft Windows, Linux, and macOS, which allows the virtualizing of the x86 architecture.  Its enterprise software hypervisor for servers, VMware vSphere Hypervisor (ESXi), is a bare-metal hypervisor that runs directly on the server hardware and does not require an additional underlying operating system.
